Andrew,
Please do.

I just tried it again.

1. Created a Mapped plain text control.
2. Saved it as a QuickPart in a template.
3. Loaded the template as a global template.
4. Inserted the content control from quick parts.
5. Copied it to another place in the document.
6. Made a change.
7. The change was not reflected in the original.

Here is a sample template that has two building blocks, one AutoText and on Quick Part. Both were created with mapped CCs that worked as such in the original document. Load as a global/add-in.
When inserted, neither inserts a mapped CC. It does insert the CCs.
